Water Levels

Water levels typically follow rainfall patterns during periods of wet weather and drought. From these data, one can get a picture of how recent flood or drought events compare to historical data. Learn more about lake water levels »

Bathymetric Maps and Depth Information

These are the latest available contour maps of the lake's bottom. These maps can be used to determine where "holes" (deep spots) exist on the lake bottom. Such areas are often productive for fishing. Learn more about bathymetric maps »

    Additional Hydrology and Geology Information

    The Lake Region Classification System is a tool used for grouping lakes based on similarities in physiography, geology, soils, hydrology, water chemistry, vegetation, and climate. It was created from a cooperative effort involving the United States Environmental Protection Agency, the Florida Department of Environmental Protection, and researchers at the University of Florida's Department of Fisheries and Aquatic Sciences. There are a total of 47 Lake Region groups. These are used to provide a framework of the different types of lakes in the state so that management plans can be developed for groups of lakes with similar characteristics.

    The lake region this lake is located in is:

    Lakeland/Bone Valley Upland (Region 7530)

    The Lakeland Ridge consists of sand hills near 200 feet in elevation with many solution depression lakes. The Bone Valley Uplands tend to be more poorly drained flatwoods area. All of these areas are covered by phosphatic sand or clay. The region generally encompasses the area of most intensive phosphate mining, but phosphate deposits and mining activities are also found south of this region. As one might expect, the dominant characteristic of all lakes in this region is high phosphorus, along with high nitrogen and chlorophyll values. The lakes are alkaline with some receiving limestone-influenced groundwater.
